CTR Insertion, Pre-IOL
Sulcus Fixation with Severe Zonular Weakness
CTR Insertion, Post-IOL
The distending force of the 3-piece IOL haptics will ovalize a round capsulorhexis if the zonules 90 degrees away from the axis of the haptics do not provide sufficient centrifugal tension. In this case, a CTR is implanted after the IOL, nicely demonstrating the mechanism of action. As the CTR redistributes the forces more evenly to the entire zonular circumference, the oval capsulorhexis becomes round once more.
